IMPROVEMENT 'IN TU RBINE WATER-WHEELS.

Specification forming part of Letters Patent No. 205,1/15, dated J une18, 1878 application filed March 30, 1878.

To 'all lwhom fit may concern: I

Be it known that I, JOHN SoHUEssLER, of Attica, in the county ofFountain and State of Indiana, have invented a new and valuableImprovement in Water- Wheels; and I do hereby declare that the followingis a full, clear, and exact description of the construc-` tion andoperation of thesame, reference ybeing had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a representation of a vertical section of mywater-wheel. Fig. 2 is a plan view, and Fig. 3 is a horizontal section,thereof. i

' The nature of my invention consists in theA construction andarrangement of a water-wheel, as will be hereinafter more fully setforth.

The annexed drawing, to which reference is made, fully illustrates myinvention.

A represents the lower part of the casing, with the bridge-tree B formedin one piece. The part Alias an outwardly-proj ecting flange, a, aroundthe top, with an offset, a', on the under side of said flange, to reston the floor and keep the heads of the screw-bolts b oft' the the iioor,which screw-bolts connect the lian ge a to a similar flange, e, aroundthe lower part of the port or chute casing C, thus holding said twocasings firmly togethe The casing G is formed with sixteen ports orchutes, d, or more, according to the diameter of the wheel, which willgive the water the ri ghtdirection to the wheel. The casing C is boredout on the inside, so that the wheel will revolve in it after beingturned off, and so that it will leave the middle bridge between theports or chutes above one-third of the width of said ports or chutes.The casing C is also turned off on the outside, so that the valves orgates D can be tted to it closely and form a water-tight joint. Thesevalves or gates correspond in number to the number of chutes d, and eachvalve is, at top and bottom, provided with an ear, f, to form hinges, sothat the valve can bel reversed, and used both for a right and leftwheel. They are also hollow on the inside, in order to reduce friction,as shown at h, to receive pins z'. These pins i, as well as the pins z",which enter the ears e ofthe valve-s, nare fastened ,in a revolvingring, E, which is formed with arms El and a central hub, E2, said hubbeing bored out to encircle the neck or pedestal F on top of the E, sothat when rotated back and forth it willv have the required throw tomove the gates far `enough to open and close the chutes d. The

ring is operated by a crank, Gr, which is held in a bearing at one endof an arm H, the

other end of which is bored out andv fits the neck F', and is heldthereto by apset-screw, k, and a key, l. The arm H answers the doublepurpose ofholdin g the crank Gr in position, and

also to hold the'revolving ring E down on the casing F and on the valvesor gates d'.

The crank G has a square hole in the upper end, and answers as a socketto receive the gate-rod or valve-rod I, by means of which the gates orvalves are opened and closed, as

required. The crank has a collar, m, on its upper end, held by aset-screw, fn, so as to support the weight of the crank and rod. Thelower end of the crank fits into a square box, J, with a round hole init to t the lower end Yof the crank, and this box works in a groove `o`rgrooved jaw cast on the revolving ring E,

so that whenthe crank is turned the boxJ will move' out and in the jawK, and thus move the ring Eto open and close the valves.

The valves or gates D are held to their seat by the pressure of thewater, and in addition I employ a springring, L, surrounding the entireseries of valves vor gates, which will hold them in place when opened orclosed without any pressure on them; and if therev should'be any`obstruction in any one or more of the ports or chutes of the casing C,this spring-ring-will1 allow such valve or valves to swing open on` itshinge, so as to slide over such obstructions, and by doing so theremainder ofthe valves or gates can be closed and the wheel stopped. Onthe upper end of the neck F is secured the bearing or follower box M, bymeans of a set-screw, p.` In this box are wooden followers r r, whichare tightened to the wheel-shaft by set-screws s s. On the top of thebox M is bolted a cover or head, N, which is formed with anupwardly-proj ectin g hub, said hub being turned at the top, as shown atx, to form a joint withametal collar, O. This collar is bored out to fitthe wheel-shaft, and counterbore'd in the under side to receive a woodencollar, P, which is turned to fit the hub of the head N. The collar O,filled with wood P, will keep all sand, gravel, or mud out of the box M,thereby preventing the cutting of the wheelshaft. The collar O willrevolve with the wheelshaft, and its own weight will keep it down on thehub of the head N.

The wheel consists, principally, of an upper rim, R, a series ofbuckets, R1,`and an exterior band, R2, around the lower ends of thelbuckets.` These buckets are straight from the upper rim R down to theband R2, and lean far enough ahead so as to form a right angle when theyare placed even with the middle bridge between the ports or chutes d.The buckets are curved and flaring down to, the lower end of the bandR2. The curved part ofthe bucket runs back past the straight line ofthebucket behind it, so as to give it a downward backward discharge. A ge l l The bandft2 is cast solid to the buckets, and forms at the top laninward flange, t, toward the straight parts of the buckets, which willmake a joint to the lower end of the port or chute 'casing G. The wheelalso opens on the lower part of the inside ofthe buckets, so as togiveit a variable discharge, Whichis effected by means of a movable ring,R3, operated by adjusting-screws o c..y These screws are worced throughhand-holes w w in the top casing F, which holes are covered by plates yy, held by suitable serew bolts. The wheel can be Iturned so as to bringthe adjustingscrews u to correspond with the hand-holes w, and then theyycan be worked with a suitable wrench, so as to raise and lower themovable ring R3, as required. By raising the ring R3 more power, and bylowering said ring it will discharge less water and decrease the power.

After thelmovable ring R3 has been set so as to givethe required power,the adjustingscrews o lvare kept from working loose by means of strapsor keepers bf, lwhich'have oblong holes in one end to` receivescrew-bolts d. In the other end'of each keeper is a squarev hole, to tover the square ends e of the adjusting-screws f1; and rest on theshoulder or collar of the same, so that when the screwbolts d' areloosened thejkeepers can be turned oft' froml the adjusting-screws, andwhen said s'cre'w's'ha've been ladjusted the keepers can be slid upagainst the square ends e', and then fastened by the screw-bolts d',andy thus prevent the adjusting-serew v from turning.

- S is the wheel-shaft, which is fastened to the wheel by a key, andruns on a wooden step, h', placed in the center of the bridge-tree B,which step can be set up by a set-screw, f', through the bottom of saidbridge-tree. The shaft S runs up through the follower-box M and collarsO P far enough to receive a coupling for suitable shafting.

By means 'of the band R2 on the wheel all the water is kept on the wheeluntil it leaves the wheel, and therefore keeps all the friction from thelower casing; and, being larger below the ports or chutes d, it willdischarge the water full and give it a greater velocity or speed.

What I claim as new, and desire to secure by Letters Patent, is-

l. A water-wheel consisting of the rim It, series of buckets Rl, andexterior bottom band R2, the buckets being straight from the rim to thetop of the band, and then inclined,V as 'described, and the bandprovided at the top with the Iinterior iange t, all substantially as andfor the purposes herein set forth.

2. A water-wheel provided with an interior adjustable bandto make avariable discharge, as herein set forth.

3. In combination vwithla water-wheel, the interior adjustable band R3,adjusting-screws t, andthe casing F, with band-holes fw andcovering-plates y, all substantially as and for the purposes herein setforth. Y
